QUARTZ SANDSTONE
Limestone Sand
The raw material of lenses is plastic polymer in most cases. There are some lenses which are made from glass materials as well.
Glass, metal, inert gas.
Coal
Glass is a compound of Silicon, Silicon is widely collected from Sand and rock
Some common problems with making glass include energy consumption during the melting process, greenhouse gas emissions from fuel combustion, and waste generation from raw material extraction and processing. Additionally, glass manufacturing can release pollutants into the air and water if not properly managed.
It is used for making petrochemicals
iron
Crushed glass is often referred to as glass cullet or glass aggregate. It is commonly used as a raw material in glass manufacturing, as well as in construction and landscaping applications.
Porcelain clay
Raw cotton grows on natural bushes, making it a natural material.
Glass batch or cullet is the colourless or brownish material used in glassmaking to produce glass. It is a mixture of raw materials such as silica sand, soda ash, limestone, and recycled glass that is melted in a furnace to create glass products.
